Abstract

The particulars of the macrostructure of rigid heat-insulating materials based on fibers with a mullite-corundum composition are examined. It is shown that the physical and mechanical properties of the materials vary over the volume of a sample. The reasons for defects are analyzed and ways to increase the isotropy of the properties of fibrous materials are indicated.
